High-per
formance workstation backup
This is a h
igh-performance graphics workstation, used by an a rchitect, who has 250 GB of data that must
be fully b
acked up every week and approximately 10 GB of changes to be backed up e ach d ay. This
data wil
l be backed up to an autoloader configured on the HP D2D Backup System.
Additio
nally, there is an ‘IMPORTAN T’ folder that relates to current, high-priority p rojects that must be
backed u
p daily and moved from the HP D2D to physical tape at the end of each week. This data will be
backed up to a standalone tape drive configured on the HP D2D Backup System.
You can specify the number of slots to meet the backup requirements for the workstation when you run the
Installation wizard, or from the Web Management interface af ter installation. You must use the Devices
pageoftheWebManagementinterfacetocreateanadditionalstandalonetapedrivedeviceforthe
‘IMPORTANT’ folder. (See “To create a new device” on page 66 for further details.)
Main backup to autoloader
The data at 250 GB exceeds the disk space that can be allocated to a single slot. Therefore, each
full backup requires two autoloader slots. You must also make sure that tape spanning is enabled
in your backup application.
